I think you mean, "That generation".....
GOOD POINT, TD.
Here is my advice to anyone using the Bible as a source of prophecy:
Before you can honestly use this book to predict the future you need to validate is authenticity. The way I did this was doing a lot of research on the Flood of Genesis.
Why is it in the Bible?
Why did God do it? What was his motivation?
Such a planetary cataclysm surely would have well documented evidence, so why is there so much contention over the event even happening?
The Flood HAS to be human history in order for the Bible to be even close to authentic enough to predict our civilization's future. And if one finds that it was indeed not human history what then? Will you become a Biblical Flood Appologetic? Or will you do the most logical thing and question the source.
